Marina Abramović is best known for her performance pieces, in which she tries to explore what is possible for an artist to do in the name of art. Her best known piece was the recent “The Artist Is Present,” in which she sat motionless for 736.5 hours over the course of three months, inviting visitors to sit opposite her and make eye contact for as long as they wanted. So many people began spontaneously crying across from her that blogs and Facebook groups were set up for those people.

Her bravest piece, however, is my favorite. This piece was primarily a trust exercise, in which she told viewers she would not move for six hours no matter what they did to her. She placed 72 objects one could use in pleasing or destructive ways, ranging from flowers and a feather boa to a knife and a loaded pistol, on a table near her and invited the viewers to use them on her however they wanted.

Initially, Abramović said, viewers were peaceful and timid, but it escalated to violence quickly. “The experience I learned was that … if you leave decision to the public, you can be killed… I felt really violated: they cut my clothes, stuck rose thorns in my stomach, one person aimed the gun at my head, and another took it away. It created an aggressive atmosphere. After exactly 6 hours, as planned, I stood up and started walking toward the public. Everyone ran away, escaping an actual confrontation.”

This piece revealed something terrible about humanity, similar to what Philip Zimbardo’s Stanford Prison Experiment or Stanley Milgram’s Obedience Experiment, both of which also proved how readily people will harm one another under unusual circumstances.

This performance showed just how easy it is to dehumanize a person who doesn’t fight back, and is particularly powerful because it defies what we think we know about ourselves. I’m certain the no one reading this believes the people around him/her capable of doing such things to another human being, but this performance proves otherwise.

This really got me thinking. Sad as it is it’s so true, and so common for people to push buttons, test the limits of others. If they realize that they don’t retaliate for some reason – often because they’re too weak to – they take advantage of the situation, at the expense of the other person. In Milgram’s experiment, participants were exposed to the sounds of the tortured and thus felt like they should stop – but in this case Abramović didn’t react to the pain or humiliation that was brought upon her.

That’s why they violated her.

What pops to mind? The nurse that ill-treated that elderly woman at the daycare. The rape of mentally-challenged girls.
